SAFETY PRECAUTIONS
!
!
!
Read this manual and all the safety precautions before attempting to
operate WerkMaster machines. Failure to follow the safety precautions may
result in severe personal injury or death. This product is intended for
commercial use.
•Wear eye and ear protection at all times when operating WerkMaster
machines. Use only ANSI/OSHA-approved safety glasses to help prevent
eye injury.
•Wear appropriate clothing and footwear when operating WerkMaster
machines. Do not wear loose clothing or jewelry that may become entangled
in moving parts.
•Crystalline silica from bricks and concrete and other masonry products may
cause health problems. Risk of exposure varies depending on how often you
do this type of work. To reduce your risk, work in a well-ventilated area, use
a dust control system such as an industrial-style vacuum, and wear
approved personal safety equipment, such as a dust or particle respirator
designed to filter out microscopic particles.
•NEVER operate WerkMaster machines under the influence of drugs or
alcohol, when taking medications that impair the senses or reactions, or
when excessively tired or under stress.
•Only operate and maintain WerkMaster machines if you are trained in their use
and are in good physical condition and mental health. You must be
physically able to handle their bulk, weight and power.
•WerkMaster machines are designed to be operated by one person at a time.
Maintain a safe operating distance to other personnel. Keep bystanders a
safe distance away during operation by blocking off the work area in all
directions with roping, safety netting, or other material. Failure to do so may
result in someone being injured by flying debris or being exposed to harmful
dust and noise.
•Maintain a safe operating distance from flammable materials. Sparks from the
cutting action of WerkMaster machines may ignite flammable materials or
vapors.
•Unplug the WerkMaster’s power cord when not in use and before servicing or
changing tooling plates.
•Turn the WerkMaster off before disconnecting power.
•DO NOT disconnect power by pulling the cord. To disconnect power, grasp the
plug, not the cord. To remove twist-lock plugs, push in and turn clockwise to
engage, and turn counter-clockwise and pull to remove.
DO NOT turn on the WerkMaster while it is tilted back. Any tooling fastened
to the WerkMaster may eject and become a lethal projectile.
•Ground this floor-finishing machine while in use to protect the operator from
electric shock. The machine is provided with a three-conductor cord and a
three-contact grounding type attachment plug to fit the proper grounding type
receptacle. The green (or green and yellow) conductor in the cord is the
grounding wire. NEVER connect this wire to other than the grounding pin of
the attachment plug.

•Be sure all safety decals on the machine may be clearly read and understood.
Replace damaged or missing decals immediately.
•Maintain WerkMaster machines in safe operating condition with all guards in
place and secure, all mechanical fasteners tight, all controls in working order,
and the grinder configured for the job application, whether concrete, natural
stone, wood or other surfaces.
•To prevent damage to your machine or severe personal injury, avoid
protruding slab inserts, nails, screws, Hilti anchors, rebar, embedded bolts or
any other debris, pipe extensions, machinery bases, or any objects that
transmit sudden shock to the grinding assembly.
•Inspect the discs carefully before installing. DO NOT use any discs that exhibit
signs of damage, as severe personal injury or damage to the equipment
could result.
•NEVER leave WerkMaster machines running unattended.
•Risk of Explosion: Floor sanding can result in an explosive mixture of fine dust
and air. Use floor-sanding machine only in well-ventilated area free from any
flame or match.
•DO NOT modify WerkMaster machines. Modifications will void the warranty
and may result in injury to persons and damage to the machine.
POWER AND CONNECTIVITY
WerkMaster machines are outfitted with a variable-frequency drive (VFD) that
allows the desired grinding speed to be selected. Along with controlling the
speed of the machine, the VFD features include the following:
•Undervoltage protection (damages most single-phase motors)
•Overcurrent protection (prevents nuisance breaker tripping)
•60 Hz and 50 Hz capability (international)
•Wide voltage range (200–230V +/- 15% for 230V models;
380–460V +/- 15% for 460V models)
•Soft start (smaller generator requirements)
•Monitor pad speed display
•Auto disabled if ON when plugged in'!
!
!
!
NEVER open the VFD panel while plugged in or immediately after
unplugging the power cord. Severe injury or death may result.
WerkMaster machines come with a variety of different plug configurations. The
following table lists the plugs that are typically used.

WerkMaster machines come in a variety of voltage and phase configurations.
The Raptor XTi is typically configured to operate on 208–230V three-phase
power. It is capable of operating on single-phase 208–230V power with the use
of the adapter cord (included), as well as 110V using a Quick 220 Adapter.
Pigtails are plug ends with unfinished bare wire on one end for hooking up to
panels. Pigtails are used when connectivity is unknown, when connecting to the
power grid of an unfinished building that has no power receptacles, or when
operating certain generators. Many pigtails are available or can be made up by
an electrician.
When using the Raptor XTi in a residential environment, source power may be
hard to find. The use of stove and dryer adapter cords make single-phase source
power easier to connect to. The dryer adapter cord is outfitted with a 30A 250V
single-phase twist-lock cord end. The stove adapter cord is outfitted with a 40A
250V single-phase twist lock cord end. The single-phase to three-phase adapter
is used to connect the dryer/stove adapter cord to the Raptor XTi only.
When using the Raptor XTi in a residential environment, source power may be
hard to find. Plug two 110V cords from the Quick 220 into the 110V wall outlet on
two (2) separate circuits. Plug the WerkMaster machine into the Quick 220
adapter.
NOTE: A 20 Amp to 30 Amp single-phase to three-phase adapter (optional)
would be required.

The dust skirt (C) serves as a seal for the bottom of the machine to act as a
vacuum chamber helping the dust stay contained under the machine. If the skirt
is too far from the ground, the dust containment is reduced.
To adjust the skirt:
1. Pull one end of the skirt off of the machine until you reach the middle of the
skirt.
2. Position the skirt until it is barely touching the ground and repeat with the other
end.
!
!
!
Avoid positioning the skirt too low as it will drag against the ground, wearing the
skirt out prematurely and possibly preventing smooth machine movement.
!
!
!
To adjust the handle, pull the pin (D). Adjust the handle to a comfortable
operating position. Re-insert the pull pin.
!
!
!
!
Failure to check the pull pin is fully reinserted could result in damage to the
machine or personal injury as the handle could release unexpectedly when the
machine is being operated or tilted back.
!
!
!
!
When the machine is first plugged in, a start-up screen will appear showing the
model of the VFD and the software version that it has been released with.
After the machine runs through its initial start-up sequence, the screen will show
the VFD status and pad driver speed in revolutions per minute (RPM).
Once the machine reaches the desired speed, the speed will remain constant as
long as the load applied remains below 100%. If the machine is running at speed
and the load begins to exceed 100%, the machine will reduce its speed as a
protective measure to try and alleviate the outstanding load. The current running
speed will be displayed. This happens under demanding conditions and is
normal.

To start the machine:
1. Apply a slight downward pressure on the handle to alleviate some weight off
the diamonds ensuring the machine does not life off the ground; then gently
squeeze the activation lever (E) and press and release the START button (F).
2. Once the machine starts, gently release the downward pressure and start
grinding.
DO NOT lift the machine off the ground while starting it. Doing so could
cause the diamonds to release from the machine, resulting in damage to the floor
or personal injury.
The speed of the machine can be adjusted when the machine is running or
stopped. To adjust the speed, rotate the speed control knob (G) on the handle
clockwise to slow it down, or counterclockwise to speed it up. Always start the
machine at the lowest speed and adjust as necessary.
!
1. Release the activation lever.
When you unplug the machine, the screen will stay lit for a few seconds as the
VFD drains the power from its internal capacitors. This is normal.
!
!
!
!
NEVER open the VFD panel while plugged in or immediately after
unplugging the power cord. Severe injury or death may result.

To install and remove the pad driver on the bottom of the machine, you will need
a 9/16” (14 mm) socket wrench, a soft face mallet, and some medium-strength
thread locker (blue Loctite 243 or equivalent).
To remove the pad driver:
1. Slip the 9/16” (14 mm) socket wrench over the pad driver bolt and strike the
wrench with the soft face mallet in a counter-clockwise direction.
2. When installing a new pad driver or re-installing an existing one, apply a
generous amount of thread locker compound to the bolt and threaded drive
shaft. Insert bolt through the hole in the pad driver. Reapply thread locking
compound every time a pad driver is removed.
3. Line up the bolt to the threaded end of the shaft and start the first couple of
threads.
4. Once the bolt is engaged, make sure that the drive shaft is properly seated
within the pad driver slot before tightening the bolt all the way.
!
!
!
Failure to seat the pad driver could result in the pad driver slot being stripped out,
the threads in the shaft being stripped, the machine leaving heavy tool marks,
and the tooling overheating.
